Ask the warlock about his choice of magic.

It's not specific to which game or book, but generally speaking, let's talk about career setting.

Mage is generally the title of a degree, which refers to a person who can control a mysterious power. It was first related to religion, and later there appeared wizards in the west who drove supernatural energy. To sum up, a mage must first have supernatural talent, and then through study and practice (or ritual? ) strengthen in talent and have abilities that ordinary people don't have in some ways.

Warlock refers to alchemists, including those who forged immortality for the emperor in the East, those who sought to forge the stone of sages in the West (the predecessor of modern chemistry, many utensils used in chemistry were invented by alchemists, and later there were scientific research methods), and more broadly, some people who are proficient in divination, astrology, geomantic omen and so on. In a way, warlocks often don't need talent. The source of warlock's ability is very complicated, which can come from knowledge, foreign objects and blood. The warlock's main purpose is research and exploration, belonging to early scientific researchers.

There are wizards and warlocks in many works:

For example, in DND rules, a mage can learn all the magic because of his talent, but the number and level of magic he can use are limited by his own strength. The warlock's strength can come from curse and blood, but he can only master some spells. The release of spells is more flexible than that of a mage, and he can awaken his own blood later to become a warlock in Long Mai.

For example, in World of Warcraft, a mage is defined as a profession that has an innate affinity for arcane energy and can use arcane energy to drift around the world. The warlock himself may be an ordinary person (or he may have been a mage, shaman and other professions). Later, he mastered and mastered the power of the devil through contracts and other means, using blood as a medium to summon the devil for his own use and using the chaotic energy that originally belonged to the devil.
